Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.
Defining a search area on the Results Map
- If you click on the Rectangle or Polygon icons in the top right of the Results Map, you can define a search area which will be added to any other search criteria already selected.
- After you have drawn a polygon, you can edit it using the Edit Geometry dropdown in the search form at the top.
- Clicking Clear in the map will clear any drawn polygon.
- Clicking Search in the map, or Search on the form will have the same effect.
- The returned results will be any projects/datasets with bounds that intersect the polygon.
- Use the Exclude project/datasets checkbox to exclude any projects/datasets that cover the whole Antarctic region.
Viewing map layers on the Results Map
To sort the table of search results, click the header of the column you wish to search by. To sort by multiple columns, hold down the shift key whilst selecting the sort columns in order.

Workshop on Antarctic Surface Hydrology and Future Ice-shelf Stability |
In February 2018, we hosted a workshop on Antarctic Surface Hydrology and Future Ice-shelf Stability at Lamont-Doherty Earth Observatory, Palisades, New York. Funding for the workshop was provided by the U.S. National Science Foundation (NSF) Antarctic Glaciology Program (award number: 1743326). The aims of the workshop were to: (1) establish the state-of-the-science of Antarctic surface hydrology; (2) identify key science questions raised by observations and theoretical studies of Antarctic surface hydrology, and (3) move the community toward answering these questions by bringing together scientists with diverse expertise. The workshop was motivated by the premise that significant gains in our understanding can be made if researchers with interests in this field are provided with an opportunity to communicate and develop collaborations across disciplines. Here we report on the organisation, attendance, and structure of the workshop, before summarizing key science outcomes, research questions, and future priorities that emerged during the workshop within the following four themes: 1. Surface melting: controls and observations 2. Water ponding and flow 3. Impact of meltwater on ice-shelf stability 4. Ice-sheet/climate modeling Finally, building on the emergent science questions, we propose a framework for prioritizing future work, aimed at understanding and predicting the impact that surface meltwater will have on future Antarctic Ice Sheet mass balance. | [] | [] | false | false |

Impact of Supraglacial Lakes on Ice-Shelf Stability |
An automatic weather station was operated on the McMurdo Ice Shelf near Pegasus Air Strip for 365 days from 24 January 2016 to 22 January 2017. The sensors consisted of temperature/RH at 2 m and 8 m (above surface), wind speed at 2 m and 8 m, 4-component radiometer, and wind direction. Time series provides averages for every 30 minutes of a 30 second sample scheme. | ["POINT(166.521 -77.936)"] | ["POINT(166.521 -77.936)"] | false | false |
